A flaw was found in OpenJDK's Abstract Window Toolkit (AWT). A remote attacker with low privileges could exploit this vulnerability by convincing a user to run untrusted code within a sandboxed environment. Successful exploitation allows unauthorized read access to a subset of accessible data, leading to information disclosure.
